Quasi gravity in branes

In contrast with pseudo-gravitational effects that are mathematically analogous but physically quite distinct from gravity, this presentation deals with a kind of quasi-gravitational effect that can act in an asymmetrically moving brane worldsheet in a manner that approximates (and in a crude analysis might be physically indistinguishable from) the effect that would arise from genuine gravitation, of ordinary Newtonian type in non-relativistic applications, and of scalar - tensor (Jordan - Brans - Dicke rather than pure Einstein) type in relativistic applications.
